Fipronil was discovered and developed by Rhône-Poulenc between 1985 and 1987, and placed on the market in 1993 under the B2 U.S. Patent 5,232,940 B2. Between 1987 and 1996, fipronil was evaluated on more than 250 insect pests on 60 crops worldwide, and crop protection accounted for about 39% of total fipronil production in 1997. Since 2003, BASF holds the patent rights for producing and selling fipronil-based products in many countries. such as shrimp and water fleas. Scientists found that fipronil is highly toxic to sea and freshwater fish, and highly toxic An invertebrate lifecycle daphnia study showed that fipronil affects length in daphnids at concentrations greater than 9.8 ppb. [5] The entire surface of the cat should be sprayed evenly, keeping the bottle at a distance of 10-20 cm from the animal. After application, it must be rubbed in so that the drug can penetrate the skin and exert its effect. Let it dry naturally without using a hair dryer or towel. You should apply it in a well-ventilated area. Pipette:

Symptoms of acute toxicity via ingestion includes sweating, nausea, vomiting, headache, abdominal pain, dizziness, agitation, weakness, and tonic-clonic seizures. Clinical signs of exposure to fipronil are generally reversible and resolve spontaneously. As of 2011, no data were available regarding the chronic effects of fipronil on humans. The United States Environmental Protection Agency has classified fipronil as a group C (possible human) carcinogen based on an increase in thyroid follicular cell tumors in both sexes of the rat. However, as of 2011, no human data are available regarding the carcinogenic effects of fipronil. [17]In contrast to neonicotinoids such as acetamiprid, clothianidin, imidacloprid, and thiamethoxam, which are absorbed through the skin to some extent, fipronil is not absorbed substantially through the skin.

Fipronil is highly toxic for crustaceans, insects (including bees and termites) and zooplankton, as well as rabbits, the fringe-toed lizard, and certain groups of gallinaceous birds. It appears to reduce the longevity and fecundity of female braconid parasitoids. It is also highly toxic to many fish, though its toxicity varies with species. Conversely, the substance is relatively innocuous to passerines, wildfowl, and earthworms. Some newer products also protect against re-infestation for longer. This is important because most of the time when flea treatment fails, it’s because it hasn’t been re-administered promptly when it was due. Bravecto oral treatments successfully prevented re-infestation for three months in a 2014 trial. What about resistance to fipronil?

In May 2003, the French Directorate-General of Food at the Ministry of Agriculture determined that a case of mass bee mortality observed in southern France was related to acute fipronil toxicity. Toxicity was linked to defective seed treatment, which generated dust. In February 2003, the ministry decided to temporarily suspend the sale of BASF crop protection products containing fipronil in France. [26] The seed treatment involved has since been banned.

However, most short-term and long-term studies find that fipronil There is no evidence that fipronil or its breakdown products evaporate from soil or water into the air. Fipronil is not

What are some signs and symptoms from a brief exposure to fipronil? It is a commonly used product for dogs and cats and quite effective as well. However, it is not labeled for horses and that’s what makes people skeptical whether they should use the spray on the horse or not.

The use of Fipronil in cats is safe and effective, but side effects such as the following may occur very sporadically: When using the spray, apply it by ruffling your pet's fur with one hand and spraying the skin and fur with the other. Do not spray the spray directly on the head or face. Spray it on a gloved hand and then gently rub it into the hair on the head. Do not get the product in your pet's mouth or eyes, and do not use on irritated skin.You might find that settling on the right treatment for you is a matter of trial and error.
